Application filed December 7, 1916.

i '0 all whom it may concern:

Be it known that we, CHARLES E. PRIOR and ROY J. TAYLOR, citizens of theUnited States, residing at Baldwinsville, in the county of Onondaga andState of New York, have invented certain new and use ful Improvements inIndicators, of which,

plates upon which the names of the various stations are marked. Afurther object is to provide an indicator having an endless carryingmedium for the plates the direction of travel of which may be quicklyand easily reversed. A still further object is to provide simple andeflicient means for moving the plate carrying medium intermittentlythrough predetermined distances.

'ects will appear from the detailed description.

In the drawings:

Figure l is a front view of the indicator;

Fig. 2 is an end view;

Fig. 3 is a vertical transverse sectional view taken closely adjacentone end of the indicator casing;

Fig. 4c is a fragmentary detailed sectional view taken through the chainand the brackets carried thereby;

Fig. 5 is a detail of the ratchet wheel;

Fig. 6 is a detail of the operating 1necha nism;

Fig. 7 is a fragmentary detail sect1on taken through the ratchet wheeland the rack;

Fig. 8 is a detail of the reversible detent for engaging the ratchetwheel; and

Fig. 9 is a fragmentary view of the drlve shaft.

The sheet metal casing 1 is'of approximately rectangular shape intransverse cross section and is'provided, at its upper edge,

with alongitudinally extending hood 2, a rectangular cut-out or opening3 bemg provided in each end plate 1 of the casingade jacent this hood.At the lower end of casing 1 a longitudinally extending shaft 5 isrotatably mounted through the end plates 4. One end of this shaft proects through one Specification of Letters Patent.

of the end plates, as at A ratchet wheel 6 is keyed on the projectingend 5 of shaft 5 and is provided, on its outer face, with a plurality ofequally spaced radially extending teeth or ribs 7 of rectangular crosssection. A. quadrantal rack 8 is loosely mounted on the projecting end 5of shaft 5 in front of ratchet wheel 6, being secured against movementaxially of the shaft by means of a collar 9 which is secured on theshaft.

The quadrant 8 is provided with a spring pressed detent 10 adapted toengage the teeth of ratchet wheel 6. The head of this detent is beveledupwardly and outwardly as at 10 The detent 10 is provided with anintegral reduced stem 11 which is slida bly mounted through the quadrant8, an expansion spring 12 being mounted about this stem and confinedbetween the quadrant and the shoulder of the head of detent 10. hisspring acts to normally force the detent toward the ratchet wheel 6 soas to engage the teeth thereof. The outer portion of stem 11 of thedetent extends through a central bore 13 in an enlarged knob or head latwhich is mounted concentric with the stem. A pin 15 is inserted throughstem 11 and projects to each side thereof, the projecting portions ofthis pin engaging into I l and com Inunicating with the central bore 13.By this means the detent is secured against rotary movement relative tothe head, while being free for outward movement. The head 1% is providedwith two diametrically opposite radially extending ears 17. These earsare adapted to engage between two spaced lugs 18 formed integral with,and extending outwardly from the outer face of, the quadrant 8. By thismeans the head 14, and consequently the detent 10, will be nor mallysecured against rotary movement.

A horizontally disposed rack-bar 19 is slidably mounted in a. bracket 20secured to of the casing l. The teeth of this bar are in mesh with theteeth 8 of the quadrant 8. A coil spring 21 has one end secured to oneend of the bar 19 and the other end secured to an angle-bracket 22secured to the end of the indicator casing. A cable 23 is secured to theother end of rack-bar 19. With the detent 10 adjusted in one position,when the rack-bar 19 is moved longitudinally away from the angle-bracket22, by exerting tension on the cable 2-3, the

otally mounted near its lower end, as at 38. The upper end of this levermay be secured to the cable 23 as at 23=k The lever 37 is provided, atits lower end, with an armature 39 which is positioned adjacent the poleof an electro-magnet 40 the ends of the coil of which are connected tothe opposite sides of a suitable source of electrical energy, such asthe battery 41. A suitable switch 42 may be interposed in the circuit ofmagnet 40. By operating this switch so as to close the circuit themagnet will be energized and will attract the armature 39. This resultsin swinging the upper end of lever 37 outward away from the drive shaft5 so as to cause longitudinal movement of rack-bar 19 thus operating thequadrant 8 and shaft 5 in the manner previously described. The raclobar19 will, in practice, be actuated, in any suitable manner, after eachstop or station which the car passes so as to indicate the succeedingstation at which the car will stop. This provides simple and etlicientmeans whereby the passengers of a car or similar vehicle may be quicklyand easily notified of the station at which the car will stop, thuseliminating all Copies of this patent may be obtained for five centseach, by addressing the danger of confusion and avoiding theinconvenience of a passenger being taken past a station at which it isdesired to stop.

There may be slight changes made in the construction and arrangement ofthe difierout parts of our invention without departing from the fieldand scope of the same, and we intend to include all such variations, asfall within the scope of the appended claims, in this application inwhich a preferred form only of our invention is disclosed.

l/Vhat we claim is:

1. In an indicator, a casing having a display opening, a plurality ofparallel spaced shafts rotatably mounted in the casing, sprocket wheelssecured on said shafts in spaced relation, an endless belt mounted aboutsaid sprocket wheels for operation across the display opening andadapted to carry indicating plates, a wheel secured on one of saidshafts and provided on its outer face with radial ribs, a quadrantloosely mounted on the shaft adjacent said wheel, a spring presseddetentcarried by the quadrant and projecting inwardly therefrom so as toengage the ribs of said wheel, said detent having its head beveled,means for reversing the detent relative to said ribs and for securing itin adjustment, and means for oscillating said quadrant about the shaft.2. In an indicator, a casing having a dis play opening, a plurality ofparallel spaced shafts rotatably mounted in the casing, sprocket wheelssecured on said shafts in spaced relation, an endless belt mounted aboutsaid sprocket wheels for operation across the display opening andadapted to carry indicating plates, a wheel secured on one of saidshafts and provided on its outer face with radial ribs, a quadrantloosely mounted on the shaft adjacent said wheel, a spring presseddetent carried by the quadrant and adapted to engage the teeth of saidwheel, the head of said detent being beveled and the detent beingprovided with a stem slidably projecting through the quadrant, anadjusting head mounted on the outer face of the quadrant andconnected'to the stem of the detent so as to prevent independent rotarymovement thereof while permitting independent longitudinal movement ofthe detent, means for securing said head in rotary adjustment, and meansfor oscillating said quadrant about the shaft.

3. In an indicator, acasing having a display opening, a plurality ofparallel spaced shafts rotatably mounted in the casing, sprocket wheelssecured on said shafts in spaced relation, an endless belt mounted aboutsaid sprocket wheels for operation across the display opening andadapted to carry indicatin plates, a wheel secured on one of said shaftsand provided on its outer face with radial ribs, a quadrant looselymounted on the shaft adjacent said Wheel, a spring pressed detentcarried by the body and adapted to engage the teeth of said wheel, thehead of said detent being beveled and the detent being provided with astem slidably projecting through the quadrant, an adjusting head mountedon the outer face of the quadrant and connected to the stem of thedetent so as to prevent independent rotary movement thereof whilepermitting independent longitudinal movement of the detent, saidadjusting head being provided with radially projecting diametricallyopposite ears and the said quadrant being provided on its outer facewith spaced lugs adapted to cooperate with the ears for securing theadjusting head in rotary adjustment, and means for oscillating saidquaddrant.

In testimony whereof we aifix our signatures in presence of twowitnesses.
